The party's coming up in just a few hours, and I've worked so hard to get the house ready for you and all your friends! I don't want to embarrass you, though, so are you sure this isn't too much cleavage? You think so? Without a bra? Noooo look at them they jiggle and bounce way too much in this dress without a bra! It's totally inappropriate for me to be asking my step-son, but are you sure? Wait, you like it? Are you getting hard right now? Do you like your step-mom's big boobs? It's ok, Sweetie, I'll put them right in your face so you can feel them and suck on my nipples,  and you can stroke that dick for step-mom until you're ready to cum all over them! Oh fuck this is way too much fun, sooo maybe if we have time we can go again before the party!
